What is vSAN and How Does It Work?

In this video, CBT Nuggets trainer Keith Barker covers vSAN. A virtual Storage Area Network can simplify your storage tasks, enhance storage performance and increase your security. Plus, if you already use VMware technology, you can get enhanced functionality when you implement your vSAN inside a vSphere environment.

When running multiple ESXi hypervisor hosts, it's possible for each of them to contribute some of their locally attached disk storage to a vSAN. There are some specific requirements for a disk to be contributed, which Keith covers. But he also covers the general logic behind creating a vSAN, configuring one and maintaining it. Watch to get a quick explanation of the power the virtual Storage Area Networks can bring to your networks.

What's the definition of high-speed network? Are we talking 100Gbe or will 25Gbe work?

Good summary but you missed the third drive, the OS disk for the hypervisor

Unhealthy disk status in vsan:
"I have 6 hosts in my vCenter that have their disks participating in vSAN.
Due to some disks testing, I had to remove one of the disks from vSAN several times and replace it with a new one.
Ultimately, this caused an "unhealthy" error to appear in the disk management section of vCenter, with a red icon next to the disk.

Now, the entire disk group is in an "unhealthy" state, and that disk group is in out of service.
Is there a hardware issue with this disk, or is there a firmware problem on disk?
I doubt it's a hardware issue since we purchased this disk recently.
If you have any solutions, I would appreciate your guidance.
Thank you.

Great intro! What tool did you use to generate those graphics and fonts?

[rohantadvi]

Sir can a device be searched using Mac address globally

It sure sounds like each host is running a VM that's the equivalent of a controller in a storage array and those VMs are running in a cluster.
